Who fits: The Bears might not be able to run their card up fast enough if Alabama's Chance Warmack or North Carolina’s Jonathan Cooper, the top two guard prospects, fell to them at No. 20.

LB Alec Ogletree

There’s a chance Alec Ogletree or Manti Te’o could be around at No. 20. Both players could step right into the middle of the Bears' defense and allow them some options in moving more versatile players who plan both inside and outside around.

Purdue’s Kawann Short and Alabama’s Jesse Williams could fit in the middle of their defensive line.

Who fits: The Lions would be thrilled if Eric Fisher falls to them at No. 5, but it doesn’t seem that’s as likely as it was a month ago. Oklahoma’s Lane Johnson has also been linked to the Lions, but he’s a bit raw having only played tackle two seasons, and might not be ready to step in right away.

There are similar question marks surrounding defensive end prospects Ziggy Ansah, Dion Jordan and Barkevious Mingo. The defensive end class is deep and the Lions might get more value in the second round with players like Alex Okafor, Sam Montgomery or Tank Carradine.

Alabama cornerback Dee Milliner could make an immediate impact as well.

Who fits: Texas’ Kenny Vaccaro, the consensus No. 1 safety, is most likely off the board, but the Packers can still get great value at their slot in Florida’s Matt Elam or LSU’s Eric Reid.

There’s the potential that Alabama’s Eddie Lacy, the top running back available, will still be on the board at No. 26. If so, the Packers could get a workhorse back to compliment Aaron Rodgers and those receivers.

Houston cornerback D.J. Hayden is reportedly moving up some boards, and might not be there at No. 23 or No. 25, but this cornerback class is deep with talent, and players like Xavier Rhodes (Florida State), Darius Slay (Mississippi State) and Johnthan Banks (Mississippi State) could all fit.
